1. A method, comprising:
at a wireless-power-transmitting device that includes an antenna array:
detecting a location of a wireless-power-receiving device;
determining settings for electromagnetic waves based on the location of the wireless-power-receiving device relative to the antenna array, such that:
(i) a maximum power level at a first distance away from the antenna array would decrease, relative to the maximum power level, by at least a predefined amount at a predefined radial distance away from the maximum power level, and
(ii) the location of the wireless-power-receiving device is within the predefined radial distance;
radiating electromagnetic waves that form the maximum power level at the first distance away from the antenna array in accordance with the settings for electromagnetic waves, wherein a power level of the radiated electromagnetic waves decreases, relative to the maximum power level, by at least the predefined amount at the predefined radial distance away from the maximum power level.
